5 Shocking Twists In Jeremiah Fisher's Journey That Redefine 'The Summer I Turned Pretty' Lore
The "golden boy" of Cousins Beach, Jeremiah Fisher, has always been the sunniest point of light in The Summer I Turned Pretty, but his journey has taken a dramatically dark and complex turn. As of this current date, December 24, 2025, the conversation around Jeremiah's character arc, particularly following the intense events of Season 3, is more polarized than ever, forcing fans to re-evaluate everything they thought they knew about Belly Conklin's second great love.
The latest season, which adapted the final book in Jenny Han's trilogy, pushed Jeremiah (played by Gavin Casalegno) to his absolute limits, transforming his easygoing demeanor into a source of heartbreaking conflict. From a shocking engagement announcement to a devastating betrayal and a final, mature confrontation, Jeremiah’s story is no longer just a sweet summer romance; it is a profound exploration of grief, loyalty, and the messy reality of young love.

The Five Defining Moments of Jeremiah’s Season 3 Arc
Jeremiah's character development in the final season of the series is arguably the most tumultuous. The show, which follows the events of the final novel, *We'll Always Have Summer*, delivers a series of dramatic highs and lows that solidify his role as the ultimate 'Team Jeremiah' heartbreak. These five moments are central to understanding his legacy.
1. The Shocking Engagement Announcement
At the beginning of Season 3, fans were stunned by the immediate escalation of Belly and Jeremiah's relationship. After a period of dating, the two proudly announced their plan to get engaged, a moment that sent shockwaves through the fandom and the Fisher/Conklin families. This decision, made while Belly Conklin (Lola Tung) was still a junior and Jeremiah was away at college, highlighted the intensity and impulsiveness that defines their relationship, contrasting sharply with the more reserved nature of Conrad Fisher (Christopher Briney).
2. The Cabo Cheating Scandal
The most polarizing event of the season, and a pivotal moment adapted directly from the book, was Jeremiah's infidelity. While away at Cabo, Mexico, Jeremiah cheats on Belly. This betrayal shattered the image of the perfect "golden boy" and forced Belly, and the audience, to confront the deeper flaws in his character. The incident immediately set the tone for the season, confirming the inevitable shift in the love triangle and serving as the catalyst for the eventual breakup.
3. The Devastating Breakup and Its True Cause
While the cheating was the immediate trigger, the breakup between Belly and Jeremiah was a long time coming. The source material suggests their split was also fueled by underlying issues, including financial stress and a growing divergence in their life paths and priorities. Jeremiah's struggle to manage his emotions and his tendency to avoid conflict ultimately contributed to the relationship's demise, making it clear that their connection, while passionate, lacked the deep-seated compatibility needed for a future together.
4. The Polarizing Fan Reaction and Actor's Response
Jeremiah Fisher has always been a polarizing character, with the fandom fiercely divided between 'Team Conrad' and 'Team Jeremiah.' Following the events of Season 3, the criticism directed at the character intensified. Gavin Casalegno, the actor, has openly addressed this intense fan reaction in recent interviews. He spoke about the "emotional negativity" and the difficulty of dealing with the fierce criticism, showing a remarkable maturity in separating himself from the flawed character he portrays.
5. The Mature Conversation with Conrad
In one of the most significant moments for the Fisher brothers, Jeremiah and Conrad finally have a mature, honest conversation about their feelings, their mother Susannah Fisher, and their shared love for Belly. This talk, which often occurs near the end of the narrative, allows the brothers to move past their rivalry and acknowledge the depth of their bond. For Jeremiah, it marks a critical step towards adulthood and emotional transparency, distinguishing him from his earlier, more guarded self.
Beyond the Love Triangle: Jeremiah's True Identity
Jeremiah’s life is not solely defined by the love triangle with Belly and Conrad. He is a complex entity with his own struggles and identity. Initially introduced as the fun-loving, athletic younger brother, he is also the one who often holds the family together, especially during the emotional turmoil surrounding Susannah's cancer.
The show's adaptation of Jeremiah also introduced the entity of his bisexuality, a trait that adds significant depth to his character, establishing him as someone who is authentically himself and flirts with everyone, regardless of gender. This aspect of his personality reinforces his image as the easygoing, magnetic "life of the party" at Cousins Beach.
The journey of Jeremiah Fisher is a cautionary tale about the difference between passion and stability. While his relationship with Belly was a beautiful, intense summer fling that extended into a serious commitment, the inherent differences in their personalities and life stages ultimately proved too great to overcome. His story serves as a powerful thematic anchor for the series, exploring the idea that sometimes, the person who makes you feel the most alive isn't the person you are meant to spend forever with.
As Gavin Casalegno prepares to "bid farewell" to the character, the legacy of Jeremiah Fisher remains a hot topic, symbolizing the sweet, chaotic, and ultimately heartbreaking nature of first loves and the unforgettable summers that change everything.
